So, the safety authority has told another icebreaker, the Aurora Australis, "to remain in open water in the area as a precautionary measure" and to be ready to render assistance. The Xue Long, meanwhile, "will attempt to manoeuvre through the ice when tidal conditions are most suitable during the early hours of 4 January 2014."

This means that the 52 passengers and scientists rescued Thursday from the MV Akademik Shokalskiy won't be getting back to Australia as soon as they hoped. They're now on board the Aurora Australis, after being flown there Thursday by a helicopter from the Xue Long, which is also known as the Snow Dragon.

Fortunately, according to the safety authority, "there is no immediate danger to personnel on board the Xue Long." The Polar Research Institute of China says the ship can carry up to 128 crew and passengers. So far, we haven't found news reports that indicate just how many people are on the Xue Long.

Also said to be safe: the 22 members of the Russian crew who remain aboard the Akademik Shokalskiy. They're keeping the ship ready to get underway as soon as conditions, hopefully, permit.

In case you're just catching up on all this, as we've said before, the Akademik Shokalskiy was about halfway into a month-long expedition when it got stuck in the ice near Cape de la Motte in East Antarctica on Christmas Eve. The Xue Long and Aurora Australis tried to break through the ice to free the Akademik Shokalskiy but couldn't reach it. So, the passengers and scientists were ferried to the Australian ship by the Xue Long's helicopter.

Or, if you prefer your highlights in Twitterish bites:

-- Russian ship carrying an Australian expedition to the Antarctic gets stuck in the ice.

-- Chinese and Australian icebreakers try to break through.

-- They can't reach the Russian ship.

-- So, a Chinese helicopter flies 52 mostly Australian adventurers to the Australian ship.
